2064104 - ESAB Neoprene O-Ring .395 ID x .040 CS

Precision Sealing for Industrial Welding Equipment

The ESAB 2064104 O-Ring is a critical component designed to maintain the integrity of pneumatic and hydraulic systems within professional welding setups. Manufactured from high-grade Neoprene (polychloroprene), this O-ring exhibits excellent chemical stability and maintains flexibility over a wide temperature range. In the context of welding equipment, the reliability of every seal is paramount; a compromised O-ring can lead to shielding gas turbulence, coolant leakage, or atmospheric contamination of the weld pool.

This specific O-ring features a precise Inside Diameter (ID) of 0.395 inches and a Cross Section (CS) of 0.040 inches. These dimensions are engineered to exacting tolerances to ensure a static or dynamic seal that meets OEM specifications. Neoprene is chosen for this application due to its balanced resistance to oils, greases, and ozone, which are common environmental factors in industrial fabrication environments. Unlike generic rubber seals that may degrade or crack prematurely under thermal cycling, this genuine ESAB part is formulated to withstand the rigors of daily operation.

Maintenance personnel and equipment technicians understand that using genuine OEM parts like the ESAB 2064104 is essential for preserving the warranty and performance standards of the machinery. Whether used in a TIG torch back cap assembly, a MIG gun connection, or a gas regulator interface, this O-ring provides the assurance of a leak-free connection. Proper installation involves ensuring the seating surface is clean and, if necessary, applying a compatible lubricant to prevent installation damage such as pinching or tearing.

By selecting the ESAB 2064104, you are investing in the longevity of your equipment. It effectively prevents the costly downtime associated with troubleshooting gas leaks and ensures that your welding parameters remain consistent by eliminating variable factors caused by poor sealing.
